I know this is more than a year since the last post, but I noticed the same problem with Vulcan not wanting to sell to end users (now they have a $200 minimum).
I wonder if anyone sorted out the spring specs to pick a replacement from McMaster-Carr?
The specs for the Vulcan spring are:
Part Number SV10G160
Torque ? 10% 4.17 in-lbs.
Thickness (in) 0.010"
Width (in) 0.500"
Length 160"
Turns 20
I.D. +-10% 1.01"
Storage Drum
1.17"
Output Drum 2.02"
Center to Center 2.25"
It doesn't look like McMaster-Carr has anything as long (160"), but a handful in the 30" - 60" +/- lengths, in the 4 +/- pound torque range.
What matters most in this type of design?
